  • Cordyceps and its allies fungi has been described as a secret medicine that gives eternal youth and a long life. Some species of Cordyceps are sources of biochemicals, such ascordycepin, with interesting biological and pharmacological properties. Hence, it has been studied to uncover its pharmacological effect. We attempted to study the formation of fruiting bodies and to develop means of mass production Korean isolate of Paecilomyces tenuipes has been inoculated into silkworms, where it reproduced using culture container, mini-kit successfully. Culture container, mini-kit is composed of a cylinder-shaped body and lid. The container is made of translucent polyethylene terephthalate. The size of the container is $82{\times}75mm$, reduced by 10 times as compared with the conventional culture kit. The mini kit has many advantages - high culture amount, ability of maintaining optimal humidity, parasite-free cultivation and high-end appearance. With the kit, the optimal cultivation condition is under $22^{\circ}C$, culture period of 53 days. And synnemata of P. tenuipes could be kept fresh for 14 days at the temperature of under $10^{\circ}C$. Therefore, the Min-kit can be used in both ways as a culture container and a packing kit for end-user customers.

  • This paper presents a sensor location decision making method respect to Container-Grown Seedlings in view of precision agriculture (PA) when sensors involved in tree container measure received signal strength (RSS) or time-of-arrival (TOA) between themselves and neighboring sensors. A small fraction of sensors in the container-grown seedlings system have a known location, whereas the remaining locations must be estimated. We derive Rao-Cramer bounds and maximum-likelihood estimators under Gaussian and log-normal models for the TOA and RSS measurements, respectively.

  • Tis study was an attempt to systematically analyze the characteristics of modern Korean food styling using the menu image photos of the Michelin Guide Seoul 2020 restaurants. The first sampling was conducted on the 27th of March 2020 and the second on the 27th of October 2020. A collection of images on the web and 442 photographic cases obtained by a search through theoretical background literature and research papers were studied by a qualitative analysis method. First, the food styling contents were analyzed and based on that, the food styling characteristics of the menus of 11 restaurants in Korea including the contemporary restaurants were considered. The analysis revealed several aspects of Korean food styling. First, food styling appeared to have three major characteristics: color, shape, and container styling. Color styling was further subdivided into single color/similar color, color contrast, source type, and accent color type. The shape/formative styling was classified into figure type, shape type, accessory type, and garnish type, and container styling was categorized as container color type, container shape type, and container material type. Second, the modern Korean food color styling characteristics of Michelin restaurants were categorized in the order of monochromatic/similar type, sauce type, accent color type, and color contrast. In the formative styling category, it was categorized in the order of shape type, small piece type, garnish/garnish type, and figure type. In container styling, container material type and formative type accounted for the major portion of the category. The food styling characteristics of the modern Korean menu were systematized and image examples were presented visually. Please use it as food styling educational material or personal food styling skill.

  • The purpose of this study was to evaluate the effects of container types on seedling growth of Chamaecyparis obtusa (2-year-old) in the container nursery culture. We used three container types [20 cavities (400 mL/cavity, $150seedlings/m^2$), 24 cavities (320 mL/cavity, $200seedlings/m^2$), and 35 cavities (240 mL/cavity, $260seedlings/m^2$)] and measured root collar diameter (RCD), height, biomass, root density and seedling quality index (SQI). The RCD, height, biomass, root density and SQI were the highest at 20 cavities/tray because this container has the largest volume and lowest seedling density. However, H/D and T/R ratio at all container types were not significantly different. The total biomass per unit area ($m^2$) were the lowest at 35 cavities/tray and those at both 20 and 24 cavities/tray were not significantly different. Container volume was positively correlated with RCD, height, biomass, root density and SQI except for H/D and T/R ratio, while seedling density negatively affected on them. Based on these results, 20 cavities/tray are optimal for container seedling production of C. obtusa. Usage of optimal container will make us get better quality seedlings and reduction of production costs in the container nursery as well as good field performances with higher survival rate in plantation.

  • The shelf life of oysters Crassostrea gigas, in two different types of packaging containers, polyethylene (PE) and polyethylene terephthalate (PET), was determined by evaluating the pH, glycogen and soluble protein content, turbidity, and viable cell count. After 7 days of storage, the pH of the packing water in the PE container decreased to 5.88, while the pH in the PET container decreased to 6.03. In the PE container, the glycogen content of the oysters decreased by 0.85 g/100 g and the soluble protein content and turbidity of the packing seawater increased by 1,927.21 mg/100 g and 3.24 McF, respectively. In the PET container, the glycogen content of the oysters decreased by 0.96 g/100 g and the soluble protein content and turbidity of the packing seawater increased by 1,674.75 mg/100 g and 0.98 McF, respectively. The reaction rate constants (K) were as follows: glycogen content, -0.18 (PE) and -0.10 (PET); soluble protein content, 0.29 (PE) and 0.26 (PET); and turbidity, 0.41 (PE) and 0.06 (PET). These results suggested that PET can be used as a new packaging container material for raw oysters because the quality is maintained and it offers more convenient handling during distribution.

  • Plant regeneration protocols for adventitious shoot organogenesis from apple (Malus domestica 'Fuji') leaf explants were developed in the present study. The effects of dark incubation periods in the early stages of culture, pre-treatment methods, the number of explants per culture container, the type of culture containers, and the orientation of the explants on culture media were evaluated to determine the optimal shoot regeneration conditions for 'Fuji' apple leaf explants. Light incubation of explants produced minimal response. However, dark incubation of explants for 4 weeks during the initial culture period enhanced shoot regeneration frequency. Comparing the number of explants per container, a higher percentage of shoot regeneration was obtained with nine explants per container compared with four explants per container. Pre-treatment, before culture, by dipping explants in a liquid regeneration medium containing 40 g/L of sorbitol for 2 hours produced the highest shoot formation rate, and the time of shoot formation was accelerated. The percentage of shoot regeneration and number of shoots per regenerating explant reached a maximum of 87.5% and 4.7, respectively. The regenerated shoots were elongated and rooted on a rooting medium of 1/4 MS with 0.2 mg/L IBA. The plantlets were successfully acclimatized, and the regenerated plants produced normal phenotypes.

  • We have developed a polyculture container which is preferable for rearing of abalones and sea cucumbers in East Sea. To test the rearing capacity of the polyculture container, 50, 75 and 100 sea cucumbers ranging from the body length of 7-9 cm were cultured in three containers including 500 abalones with the shell length of about 5 cm, respectively. It was revealed that preferable density for sea cucumbers was 52-72 individuals in the polyculture container. Glutamate oxaloacetate transaminase and glutamate pyruvate transaminase were analyzed with Reflotron kit to investigate the health degree of abalones in two polyculture containers including 300 and 500 abalones with the shell length of about 5 cm. Glutamate oxaloacetate transaminase has been an important tool to know myocardial infarction, disease of liver, and destruction of muscle. Next experiment was conducted to determine the effects on growth of abalones and sea cucumbers in polyculture container. Experimental findings, RNA/DHA ratio, DNA and RNA contents (ug/mg) were not significantly different among all groups. The results imply that the method of polyculture can be rearing with sea cucumber without growth retardation of abalone. Production ability between polyculture container and the container used in south sea were carried out using suspended culture method during 8months. It was revealed that abalones and sea cucumbers are faster growing in polyculture container than in container used in south sea. Therefore, polyculture container is considered more appropriate for the abalones and sea cucumbers culture in East Sea.

  • The purpose of this study was to analyze the planning characteristics and it's applications of container architecture in Seoul and Kyunggi Area. A document research and field survey were used to analyze and classify the spatial characteristics of the container architecture since 2009. Based on the results of the critical review, this research proposed a framework to identify the potential of the container architecture for sustainable and flexible planning. The framework was composed of four dimensions such as flexibility, rapidity, sustainability and economic feasibility. The types of space construction were dynamically self-erecting structure, incremental structure, mobile and disposable architecture. The spacial aspects were commercial spaces, housing spaces such as dormitory and urban compact apartments, and the multi-purpose spaces such as gallery and culture space as well as temporary spaces. It attempted to resolve the concept of flexibility and mobility through the experiment so that they might apply to the space of contemporary city.

  • This study was carried out to investigate the growth characteristics and root development of Mandshurian Linden (Tilia mandshurica Rupr. et Max.) seedlings grown in plastic net container and plain plastic container. The seedlings were grown in the mixture of peatmoss perlite : vermiculite (1:1:1, v/v/v) for five months in the plastic greenhouse. The seedlings grown in plastic net container showed greater root collar diameter growth, better root development, and more increment of root dry mass than those grown in the plain plastic container. In particular, the seedlings grown in plastic net container had no spiraling roots which were always observed in the control . These results suggest that the net container is suitable for container culture of Tilia mandshurica seedlings by enhancing root development. Seedlings grown in the net container and transplanted to various environments showed vigorous rootage and growth.
